Red Hat WT8551A017MS 5-Way Pilot Solenoid Valve 120VAC 1/4" Orifice

SKU CH-STTV-D8W8G MPN WT8551A017MS

A 5-way pilot solenoid valve controlling air and inert gases at 120 VAC with a 0.86 Cv rating

  • Product typeDrain Components
  • 5-way universal valve directs air or inert gas flow
  • 120 V AC coil actuates reliably in indoor or outdoor settings
  • 30 psi minimum differential ensures positive pilot operation
  • Anodized aluminium body with NBR and polyurethane seals resists corrosion
  • Cv 0.86 orifice delivers consistent flow capacity

5-Way Pilot Solenoid Valve

The Red Hat WT8551A017MS is a 5-way 2-position pilot solenoid valve built for air and inert gas control. It suits process, automation and fluid-power engineers who need reliable directional switching in a compact body.

Sustained Pressure Operation

Rated for continuous duty between 30 psi minimum and 150 psi maximum differential the valve maintains stable pilot response without pressure drop. Anodized aluminium body and Class F coil insulation handle extended cycling in indoor or outdoor installations.

1/4 NPT Universal Mounting

Universal 1/4 inch NPT ports and a 1/4 inch orifice with a 0.86 Cv factor simplify piping in tight manifolds. NBR and polyurethane seals resist standard compressed-air lubricants while the 120 VAC coil offers direct mains connection without extra transformers.

Questions about this item

How much heat does the 120V AC coil generate during continuous operation?

The coil uses Class F insulation rated for higher temperatures, so it handles the heat from extended energising without degradation.

What piping and pressure source are required to install this 1/4" NPT valve?

You need 1/4" NPT fittings and a compressed-air or inert-gas supply between 30 and 150 psi differential to meet the pilot-operated design.

Will the anodized aluminium body and NBR seals withstand the same shop air as my older brass valves?

Yes, the anodized aluminium body and NBR/polyurethane seals are compatible with standard lubricated or dry shop air and inert gases.
